Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an e-type facial cleanser, and more specifically, it spreads easily on the skin, has excellent oil and fat absorption efficiency, and has a smooth appearance after washing with water. The present invention relates to a quick-drying face wash that provides a comfortable feeling when used and can suppress oil lifting and makeup smearing.

[Conventional technology]

Traditionally, commonly available face washes with the main purpose of oil-absorbing properties include kaolin, Merck, bentonite,
Based on highly oil-absorbing powder such as anhydrous silicic acid, hydrated silicic acid, and calcium carbonate, ? Most of the products contained lyols, ethanol, pigments, fragrances, water, etc. This type of highly oil-absorbing powder is used as a base. When the e-tsuk type facial cleanser was applied to the skin, sebum shunted from the skin dried on the skin. It rises over time through the gaps between the powder particles of the e-touch type facial cleanser and is retained between the powder particles, so it has the effect of preventing makeup from fading after the face wash is applied.

Therefore, in order to fully exhibit such effects, it is necessary to contain a large amount of powder with good oil and fat absorption properties to increase oil and fat absorption, and to dry quickly. For this purpose, a method has been proposed in which, for example, an acidic buffer is contained in the base to increase its oil and fat absorption, thereby improving the makeup's longevity and feel during use (Japanese Patent Application Laid-open No. 163807/1983).

[Problem that the invention seeks to solve]

However, conventional pack-type facial cleansers are not fully satisfactory in terms of both oil-absorbing properties and quick-drying properties, especially when oil-absorbing powders that swell with water are used.

If the amount of the compound is increased, it may form into glues and the viscosity of the entire system will increase, making it difficult to spread when used. Since the body is hydrophilic, the drying speed is slow.

[Means for solving problems]

As a result of various studies to overcome these problems, the present inventor found that by blending oil- and fat-absorbing powder, water-repellent powder, hydrophilic nonionic surfactant, and water, a larger amount of powder than ever before can be produced. The present invention was completed based on the discovery that a product that can be blended into the skin, spreads well, has excellent drying properties, and has high oil and fat absorption efficiency when applied to the skin.

That is, the present invention provides oil-absorbing powder, water-repellent powder %HLB
The present invention provides a quick-drying, Q-tsukou facial cleanser characterized by containing a nonionic surfactant of L2-18 and water.

The oil-absorbing powder used in the present invention includes:

For example, clay minerals or organically modified bentonites such as natural or synthetic bentonite, kaolin, and talc; inorganic powders such as sericite, mica, silica, silicates, zeolites, diatomaceous earth, barium sulfate, and calcium carbonate;
Limethyl methacrylate, -9 vinyl chloride, ? Lipropylene, acrylic acid derivative? Rimmer, nylon, e-wooder,? Examples include organic powders such as listyrene, among which bentonite and silica are particularly preferred. These alone,
It can also be used in combination of two or more types. The amount of oil-absorbing powder is usually 1 to 50% by weight based on the total composition.

Preferably, it is blended in an amount of 10 to 20% by weight.

The water-repellent powder used in the present invention is preferably one obtained by treating the oil-absorbing powder with silicone, metal soap, etc., and silicone-treated Merck is particularly preferable. As a method of water repellency treatment, 1. For example, the above oil-absorbing powder may be treated with Zometel? Methyl hydrozoene? It can be obtained by mixing it with a silicone oil such as resiloxane and heating it, or by stirring the powder and aluminum sulfate in a suitable solvent, adding metal soap, and drying after removing the solvent. These can be used alone or in combination of two or more. The water-repellent powder is usually 1 to 50% of the total composition.
It is blended in an amount of 10 to 30% by weight, preferably 10 to 30% by weight.

The nonionic surfactant used in the present invention is HLB
Hydrophilic ones with a value of 12 to 18 are suitable, for example:
? Lioxyethylene hydrogenated castor oil, oxyethylene glycol fatty acid ester, ? Lioxyethylene alkyl ether,? Lioxyethylene solpitan fatty acid ester, fatty acid? Lyoxyethylene glyceryl, fatty acid?
Examples include those having an HLB value of 12 to 18, such as lyethylene glycol and polyoxyethylene alkylphenyl ether, which can be used alone or with 2'! ! 11 or more can be used in combination. Non-ionic kaiyami activator.

Q is usually added in an amount of 1 to 3.0% by weight based on the total composition.

Moreover, it is preferable that water be blended in a range of 30 to 70% based on the total composition.

In addition to the above-mentioned ingredients, the quick-drying/Q-shaped head pigment of the present invention also includes humectants such as propylene glycol and glycerin, which are used as ingredients in known cosmetics; drying aids such as ethanol; and inorganic [, 1116M Alcohol, viscosity modifiers such as hydrothousandimethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, methylcellulose, sodium carboxymethylcellulose; anti-inflammatory agents such as zopotassium glycyrrhizate; other fragrances, 1 pigment, ultraviolet absorber, acidic buffer, antioxidant. Agents, bactericides, preservatives, etc. can be added as necessary.

[Function] When the quick-drying face wash of the present invention is applied to the skin, water between the powders contained in it evaporates quickly, depending on body temperature or humidity in the air. Since gaps are created between the powders, the gaps act as capillaries, allowing the sebum secreted from the skin to be efficiently sucked up by capillary action.

〔Effect of the invention〕

The quick-drying/Iil-type facial cleansing type top pigment of the present invention has excellent drying properties, so it can efficiently absorb sebum secreted from the skin, and it is possible to suppress oil floating and makeup smearing after washing the face. In addition, since it can be easily washed away with water, there is no residual feeling of powder, giving a refreshing feeling of use.
